HPV vaccine is safe and effective, review finds

An international review of the HPV vaccine has found it's both effective and safe.

The study, published in the Cochrane Library, looked at 73,000 women, and found the vaccine protects against cervical lesions.

It also found the injection did not appear to increase the risk of serious side effects, such as miscarriage.

In New Zealand, the vaccine is free for anyone aged between nine and 26 years old.

Trump says Iran re-starting nuclear programme would lead to 'severe consequences'

President Donald Trump warned Iran on Wednesday (overnight NZT) against resuming its nuclear weapons program, a day after announcing that he was withdrawing the US from the landmark Iran nuclear deal.

"I would advise Iran not to start their nuclear program," Trump told reporters at the start of a Cabinet meeting when asked about the potential consequences. "I would advise them very strongly. If they do there will be very severe consequence."

The comments came a day after Trump announced he was withdrawing the US from the accord with Iran, abruptly restoring harsh sanctions in the most consequential foreign policy action of his presidency.

He declared he was making the world safer, but he also deepened his isolation on the world stage and revived doubts about American credibility with a rationale that contradicted the analyses of US and foreign intelligence sources.

The 2015 agreement, which was negotiated by the Obama administration and included Germany, France and Britain, had lifted most US and international economic sanctions against Iran.

In exchange, Iran agreed to restrictions on its nuclear program, making it impossible to produce a bomb and establishing rigorous inspections.

But Trump, a severe critic of the deal dating back to his 2016 presidential campaign, said Tuesday (yesterday NZT) in a televised address from the White House that it was "defective at its core."

On Wednesday, he claimed the deal "was going to lead to nuclear proliferation all over the Middle East" and bragged the sanctions would be among the strongest "that we've ever put on a country."

Trump also pointed to Iran's actions in countries including Syria and Yemen.

"With all of the places they're involved, it's bedlam and death and we can't allow that to happen," he said, adding: "They've gotta understand life. 'Cause I don't think they do understand life."

US allies in Europe had tried to keep Trump in and lamented his move to abandon it. Iran's leader ominously warned his country might "start enriching uranium more than before."

The sanctions seek to punish Iran for its nuclear program by limiting its ability to sell oil or do business overseas, affecting a wide range of Iranian economic sectors and individuals.

Major companies in the US and Europe could be hurt, too. Treasury Secretary Steven Mnuchin said that licenses held by Boeing and its European competitor Airbus to sell billions of dollars in commercial jetliners to Iran will be revoked. Certain exemptions are to be negotiated, but Mnuchin refused to discuss what products might qualify.

He said the sanctions will sharply curtail sales of oil by Iran, which is currently the world's fifth largest oil producer. Mnuchin said he didn't expect oil prices to rise sharply, forecasting that other producers will step up production.

Iran's government must now decide whether to follow the US and withdraw or try to salvage what's left with the Europeans. Iranian President Hassan Rouhani said he was sending his foreign minister to the remaining countries but warned there was only a short time to negotiate with them.

Trump also left open the possibility of a new deal, and told reporters Wednesday: "We'll make either a really good deal for the world or we're not going to make a deal at all. He predicted Iran would choose to negotiate eventually, or face consequences.

The administration said it would re-impose sanctions on Iran immediately but allow grace periods for businesses to wind down activity. Companies and banks doing business with Iran will have to scramble to extricate themselves or run afoul of the US government.


The Kiwi dentist with a new approach to treating tooth decay in children

A Kiwi dentist thinks we should ditch convention and start looking at tooth care in children when they're still babies.

Professor Mark Gussy says the earlier we identify possible teeth problems the better.

"If you have tooth decay as a child its predictive of lifetime cavities," Professor Gussy told TVNZ1's Seven Sharp.

New tests mean dentists are able to check for tooth decay in babies who don't have teeth yet by testing their saliva.

The test looks at the mix of bugs in the babies mouth as a way to predict any possibilities of decay later on.

"Two is too late (for checkups) once diet is established at two that's it. We are interested in the first year or two of life," Professor Gussy said.

The test is aimed at preventing problems before school starts and Rhode Street School in Hamilton is on-board with the oral hygiene revolution, banning fizzy drinks and other sugary treats.

This kind of action is welcome in New Zealand with a study out this week showing over 6000 Kiwi kids needed hospital treatment for severe decay in just one year.
